The current situation is very reasonable, in my opinion: numpy has two Mac binary distributions for Python 2.7: 32-bit 10.3-and-up and 64-bit 10.6-and-up. These match the python.org python distributions. I can't see wanting any more than one per python.org Mac binary. Note that the numpy Mac binaries are not listed next to each other on the numpy sourceforge download page, so some folks are installing the wrong one. If you add even more os-specific flavors the problem is likely to get worse. -- Russell _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
